Michael Fassbender who recently starred as Magneto in "Xmen: First Class" is currently signed to star in upcoming movie based on Ubisoft's Assassin's Creed. He will also co-produce the movie. The movie will likely loosely follow the plot of the video game franchise, though it's unclear if it will cover the exploits of the assassin from the first title, its more successful sequels, or even the soon-to-be-released Assassin's Creed 3.
